However, an arrest warrant was issued for her lover after he failed to turn up at court on Friday to be sentenced.

Helen Juby, 36, of March, stood in the dock alone after he failed to turn up at Cambridge Crown Court.

The court was told that police were alerted by a member of the public and when officers arrived in Tillery Field Park, off Alexandra Road, Wisbech, one girl of 12 among a group of youngsters aged from 10 told a Pc: “You don’t want to go over there. They are disgusting people.”

Juby, of Highfield Road, and Lithuanian Andrius Vaiciulevicius, 30, of Norwich Road, Wisbech, both previously pleaded guilty before magistrates to outraging public decency on September 2.

At the sentencing hearing Judge Nicholas Coleman issued an arrest warrant for Vaiciulevicius.

Judge Coleman told Juby: “You decided to have sexual intercourse with this man. It was for all to see, it was mid-afternoon, it was a park, with children nearby and indeed a child attracted the attention of the police officer.

“You clearly don’t think that Sundays should be a day of rest, certainly from sexual activity.”

Prosecutor James Earle said police could smell alcohol as they approached the couple. Neither of them had any clothes on from the waist down.

Juby told officers when arrested she didn’t know who her partner was, said the prosecutor.

Mitigating, Andrew Cogan said Juby was remorseful and knew it was wrong.

He continued: “She said sorry to police and that she had told the man they should have gone to a house and made love there, not in the park.”

Councillor James Palmer, leader of East Cambridgeshire District Council, has thrown his hat in the ring to become the new Mayor of Cambridgeshire and Peterborough, with hopes to “improve infrastructure and provide high quality housing for all”.
